Title: Magnetic bubble device
Inventor: HONMA ROKUROU
IPC: G11C11/14
Filed: 1981-11-24
Abstract: PURPOSE:To obtain a magnetic bubble device having a high speed and high density, by forming a magnetic bubble transfer path with a conductor layer having rectangular non-conductive parts and a square conductor layer which is laminated with insulation to the preceding conductor layer. CONSTITUTION:A conductor layer 7 provided with rectangular non-conductive part 9 and the square conductor layer 5 which cover about half of the part 9 at the one side via an insulated layer are laminated on a magnetic thin film formed on a substrate. Then the layer 5 is connected electromagnetically to the part 9 to form a magnetic bubble transfer path. It is possible for the conductor layer to transmit a high frequency current since its inductance component is reduced owing to the constitution of a single plane conductor. Thus a high-speed drive is possible by a high-speed rotary magnetic field. As a result, a magnetic bubble device having high density is obtained in an easy way of production.

Title: Tab set display system
Inventor: ABE SHINTAROU
IPC: B41J21/18
Filed: 1980-12-29
Abstract: PURPOSE: To improve operatiliby such as editing operations, by a method wherein, in an indicator which displays letters, being different in letter width, in the same width, when encounting with a TAB code, a TAB displaying mark is shifted so as to coincide with a real TAB position.  
     CONSTITUTION: In case a transfer data is i...(i=8) TAB, at a point of time when 8 pieces of i are transferred, the number (8) of a data i, a value (48) which is addition of the unit number (6) of i by the number of i, and contents (48) of a register 7÷10 (standard unit number) are loaded in a first address pointer 2, a horizontal position register 7, and a second address pointer 10, respectively. Then, when a TAB data is transferred, it is incremented until a vale b of the second address pointer 10 coincides with the TAB position of the TAB register 10, and a TAB display (▿ symbol) is shifted until the value b coincides with a value (a) of the first address pointer 2. This causes coinciding of an actual printing position with a TAB display position on a display device.
